why else - overweight. I do a 20km run daily but have been put off by the way my bodies sugar addiction affects me
Fruit.
It has sugar and it's good for you, don't believe this BS that fruit will make you fat. Perhaps fruit juice yes because the pulp/fibers and what not has been removed so the sugar uptake is higher than eating the fruit but add as much fruit to your diet as possible.
They reckon you should eat 5 different fruits a day. You could also be suffering from a bad carb withdrawal but if you eat stuff like oats and fruit you should not have a withdrawal from anything. I have no idea what your diet is but some people think cutting out sugar will solve their fat issue but it won't. Your body needs sugar for energy and it should not convert into fat unless you sit on a couch all day. You run 20km's so unless you are eating 5 chocolates, 3 bags of chips and pies i don't see why you are cutting out an energy source.
Sugar withdrawal has so many symptoms you are bound to be feeling a few of them. It's like depression, 99% of people will have some of the symptoms, does that mean they need drugs?

You do not need to go without any sort of sugar you just need to eat a good balanced diet which would include a choccie or two, chips, the odd take out. It's all about too much.
Wow my body would shut down with that diet

. Replace wheat bix with oats
The bread you are eating is also going to turn into sugar
Our bodies break carbohydrates down into sugar and then burn the sugar as
So you think you are having no sugar but the bread would suggest otherwise.

Your body seems to be telling you that you are not giving it what it needs. Seems like it's saying hey buddy you are starving me!!!!!!! Not enough fruit, where is the salad? You need to google foods that help you lose weight because you are eating none of them except apples

. Starving your body won't lead to weight loss long term.

For lunch you really should look into a chicken/tuna salad with tomatoes, cucumber, feta, avo
For breakfast a grapefruit would be ideal along with oats/eggs. If you gonna eat bread buy whole wheat, my fav is woolies seed loaf.
